I especially enjoyed this bit:
Ironically, [Michelle] Rhee’s successors at DCPS have redesigned teaching through some of the very policies that teachers’ unions and other Rhee adversaries opposed most strongly: comprehensive teacher evaluations, the abandonment of seniority-based staffing, and performance-based promotions and compensation. They combined these with other changes, like more collaboration among teachers, that these same critics had backed. Just as notably, the transformation is taking place not at charters but in the traditional public school system, an institution that many reformers have written off as too hidebound to innovate.
Could those "hidebound" regular public schools be responding to increasing, intense competition from charters? Hmmmm . . .
